Jailbroken iPhone 4 BB 4.10.01 Cellular Signal Dropping

Hello guys, I have a slight problem on my iPhone 4. Lately, I’ve been noticing that my signal’s been dropping out. This issue occurred after jailbreaking my iPhone 4 on iOS 4.3.3 using JailbreakMe 3.0.  So, do I need to upgrade to the latest iPhone firmware? Thanks in advance.

Hello Sned, as much as possible, I would recommend you to STAY AWAY from iOS 4.3.5 or do not restore your iPhone directly using iTunes. Though, restoring your iPhone to the latest iPhone firmware might fix the issue, however this process will lose your jailbreak, downloaded and installed apps, saved photos and videos, etc…

Anyway, you can try to download and install Ultrasn0w 1.2.3 to fix your device. If you aren’t familiar with the steps, then you can follow the step by step geode posted below to install Ultrasn0w 1.2.3:

Step 1: Launch Cydia app on your jailbroken iPhone.

Step 2: Then tap on the Manage tab at the bottom of Cydia followed by tapping on Sources section to view your current Cydia repos. If you see already added in your current sources list, jump to step 4 otherwise continue to the next step.

Step 3: Now you have to tap on the Edit button and followed by tapping on Add button. Then enter as Cydia/APT URL and hit Add Source button.

Step 4: Wait while Cydia updates its database. Once done, hit the Search tab and type Ultrasn0w in the search field.

Step 5: From the search results, select Ultrasn0w and tap on Install button.

Step 6: Cydia will now install Ultrasn0w 1.2.3 on your iPhone. Once completely installed, tap on the Reboot Device button to restart your iPhone.

Step 7: After installing Ultrasn0w 1.2.3, you can check your cellular signal strength by dialing *3001#12345#* and then compare your signal strength to other iPhone or smartphones.

That’s it!
